LOINC® (Logical Observation Identifiers Names and Codes) was developed to provide a definitive standard for identifying clinical information in electronic reports.
The LOINC® database provides a set of universal names and ID codes for identifying laboratory and clinical test results and is widely used in HL7 messages. One of the main goals of LOINC® is to facilitate the exchange and pooling of results for clinical care, outcomes management, and research. LOINC codes are intended to identify the test result or clinical observation and the use of LOINC® is a requirement of the Meaningful Use program.
LOINC® codes are also used to exchange health data, such as lab values and vital signs in the NCPDP SCRIPT Standard.
LOINC® version 2.61 and RELMA® version 6.20 are now available for download from the loinc.org website.
